Did You Know?

1. Did you know that grout was originally made from a mixture of sand, water, and lime? Over time, different materials have been incorporated into grout to enhance its durability and effectiveness, including Portland cement and polymer additives.

2. Have you ever wondered why grout cracks in shower corners? One possible reason is the shrinkage that occurs during the grout drying process. As the grout dries, it loses moisture, leading to a reduction in volume and potentially causing cracks, especially in areas with greater movement, such as corners.

3. While filling cracks in the grout is a common solution, an alternative method is to add flexible caulking instead. This flexible material, typically silicone or polyurethane-based, can withstand the movements that occur in shower corners and is less likely to crack over time.

4. Did you know that the size of the grout joint can also affect the likelihood of cracks forming in the shower corner? The narrower the grout joint, the greater the chance of cracking due to the increased stress concentration. Maintaining a wider grout joint may help reduce cracking.

5. To prevent future cracking in shower corners, consider using an expansion joint or a movement joint during the initial grouting process. These joints are designed to absorb the natural expansion and contraction that occurs in structures, reducing the stress on the grout and minimizing the likelihood of cracks forming.

1. Common Reasons For Grout Cracking In Shower

Cracked grout in a shower corner is a frequent issue faced by homeowners. Although grout is generally durable, damage can occur over time due to various factors. The two most common causes of grout cracking in a shower are age and movement.

The constant exposure to moisture and fluctuating temperatures in a shower can gradually weaken the grout and make it more prone to cracks. Moreover, the natural movement of a house can also contribute to grout cracking. As a house settles or experiences minor shifts, the grout in the shower corner may be subjected to stress, ultimately resulting in cracks.

2. Supplies Needed For Repairing Cracked Grout

To effectively repair cracked grout in a shower corner, you will need a few basic supplies: grout, a grout saw, a vacuum, grout trowels, a mixing trowel, a plastic container, and rags.

The grout saw is used to remove the old grout, while the vacuum is necessary to clean up any fallen grout and debris. The grout trowels and mixing trowel are used to apply the new grout. The plastic container is essential for mixing the grout to the proper consistency. Rags are used to remove any grout film on the tiles during the cleaning process.
